CAR-Axdia Box."`

SPECIFICATION forming-part of, Letters Patent No. 416,890, datedDecemberio, 1889; Appiimion nea Juiy 13,1889.'` sensi No. 317,413. (Nomodem.

Be it known `that I, ELIAS U. BENEDICT, a

'citizen of the United States, residing at Au-` rora, in the county ofKane and State of Illinois, have invented a new and useful Improvementin Car-AxleA Boxes, of which the `following is a specification..

My invention relates particularly to an improvementin the lid forcovering the opening.le'ading to the interior of the axle-box for ajrailrQad-c'ar, and it relates .especially to an improvement on theconstruction of lid for the inclined box-opening secured in position bya pivot-bolt surrounded by a spiral spring confined between a head onthe bolt and the outer surface of the lid, and designed to exertpressure against the latter and thereby tend to maintain it when closedagainst its seat, the lid being thus adapted-to be turned on its pivotto open and close thebox.

The object of my invention is to provide a construction of axle-boxwhich when closed shall effectually cover the opening of the box it isdesigned to shield, which shall tend to prevent oil thrown from the axleby its rotation against the inner surface of the boxlid from escaping toand running down the outside ofthe box, and which shall be capable'ofready manipulation for opening and closing the axle-box.

In the accompanying drawings, Figure l is a sectional view in sideelevation of an axlebox shown as in position on 4the axle and providedwith a lid of my improved construction; Fig. 2, a section taken on theline 2 of Fig. 1 and viewed in the direction of the arrow; Fig. 3, anupper plan view of the lid, and Figfi a broken perspective View showingthe outer inclined end of the box and the seat for the box-lid.

A is an axle-box of ordinary or suitable construction, and having a seatr at three inner sides of its opening B, and a perforated lug s,extending from the end at which the lid is pivoted,vas hereinafterdescribed, the upper surface of the'lug and end from which it extendsbeing iush with that of the seat r. The lateral upper and lower marginsp and q may be, so far as their guiding function is concerned, the sameas on other axle-boxes, though I prefer that the latter should serve asa stop to the turning of the lid,hereinafter .n described, downward ortoward the left from its closed position, and that the former should bebeveled on its front side from near its left hand to its opposite end topermit the lid to passover it the more readily in being turned to openthe box. The left-hand margin fr of the opening Bl should be somewhatoblique on its inner side,` as i shown, or otherwise adapted to fit thefree "edge of the box-lid. i

C is the lid, conforming in general shapeto v that of the opening B, andhaving formed on its outer side, near one end,`a lug si', like'the lug son the box, and a pocket D, and it is somewhat beveled, by preference,or otherwise ladapted at its opposite end to fit against thecorrespondingly-beveled margin Maud provided near its beveled end with ahook o or analogous means, toserve. a purpose hereinafter explained.

A bolt n or pin is passed through elongated openings m, formed in thetop and base of the pocket, and through an opening in the lug s" of thebox-opening B, being fastened by a nut lo on its inner end and providedwith ahead t' at its outer end, between which head and the surface ofthe pocket is confined a compressed spiral spring h around the bolt.Inside `the pocket is a spring confined at opposite ends,

respectively, between the pivot-bolt at, thus affording a stop, and theforward wall of the pocket, which thus constitutes a spring-seat, andmay be modied as to construction without impairing it for its purpose.

When the lid is closed, the spring (which has been compressed by openingit) holds itwith its free edge against` the margini", and if the latterand the lid be beveled, as described, and as it preferably is, the lidis also thereby confined against `being forced outward by pressureagainst its inner side, and thus assures tight closure of the box. Toopen the box, the operator, who should employ a suitable instrument i'or the purpose, as a rod with a hook formed on one extremity, appliesthe instrument to the hook o, to pull the lid against the spring g, atthe same time slightly raising it toward the freel end from its seat toclear the margin p, when itis free to be turned y to the right touncover the opening B. The

IOO

lid is again pulled against the spring g and turned on its pivot tillcoincident with its seat, when it is released and shot forward by theresilience of the Spring compressed by the withdrawal of the lid.

The point of pivoting the lid need not be at the right-hand side of thebox, but may be, if desired, at the top of the box-opening, when ofcourse the beveled margin p could be provided at the right-hand side ofthe opening, the margin q at the opposite side and the margin 1" at thebase o'll the opening.

A further advantage, due to my improved construction, consists in thetendency of the lid C to retain in the box all oil thrown against itsinner side from the axle by its centrifugal action, by causing the oilthus thrown to drip down inside the box, there-by Saving it and tendingto keep the outside of the box clean. As .the covers of axle-boxes havehitherto been commonly constructed the inside surface of the cover isonthe outside of the box,`whereby oil thrown against the inner side of thecover runs down on the outside of the oil-box and is not only-thuswasted, but tends to produce accumulation of dust. Asr will be clearlyseen on inspection of Fig. 1 of the drawings, the loweredge of the lid Cis flush with the inner surface of the base of the oil-box, the downwardinclination of which is regular from the opening B in the sense that itis devoid of such irregularities as would afford lodgment to oiltrickling down the lid, and would lead the oil to the exterior of thebox.

lith my improved construction obviously all the oil which is thrown'against the inner side of the box-lid must runV back into the box and besaved.

That I claim as new, and desire to secure by Letters Patent, is-

l. An axle-box lid having a lug s', extending from one end, a pocket D,formed on the top of the lid and lug and provided with an elongatedopening nl, extending transversely through it and the lug s', a bolt n,extending' through the elongated opening and having a spring 7L,confined upon its outer projecting portion, and a spring q, confined inthe pocket between an end thereof and the bolt n, substantially as andfor the purpose set forth.

2. In combination, an axle-box A, having a perforated lug s at one sideof its opening B, and a lid C, having a lug sf, extending from one end,a pocket D,'forn1ed on the top of the lid and lug s and provided with anelongated opening fm, extending transversely through it and the lug s',a bolt An, extending through the elongated opening and perforated lug sand havinga spring 71, conlined upon its outer projecting portion, and aspring q, confined in the pocket between an end thereof and the bolt fn,substantially as and for the pur pose set forth.

3. In combination, an axle-box A, having an opening' B, and its baseregularly inelining downward from the opening, and alid C, adjusted tocover the opening, with its inner surface entirely within the box andwith its lower edge flush with the lower inclined inn ner surface of thebox, substantially as and for the purpose set forth. Y

4. In combination, an axle-box. A, having a seat r for the lid and amargin r al one side of its opening B, a stop-margin q at the base, abeveled margin p at thel top and a lug S at the opposite side thereof,and aA lid C, provided toward one end with a lug s and with a pocket I),containing a spring g and having elongated vopenings lmy, av pin n,extending through the openings on and lug s and pivotally securing' thelid to the box, and a hooko or the like on the lid, substantially asdescribed.
